Listed below are tips for streamlining the order process:
Specify grounding provisions for each base. Internal lug, external lug or both.
Specify anti-rotation fins (factory-installed on the sides of bases) by quantity and size/configuration.
Specify anti-uplift bars (factory-installed on the bottoms of bases) by quantity and size/configuration.
Specify spacers with O-ring and gland (flange ring) or without (spacer ring)
Specify epoxy dam rings on spacers with O-ring and gland (Y-flange ring) or without (Y-spacer ring)
Specify conduit couplings (factory-installed) by quantity, size and location.
Specify grommeted openings for conduit by quantity, size and location. Make certain to identify the type(s) of conduit to be used as different types and / or conduit coatings may change the OD and thus the grommet size.
Do not specify bolts longer than necessary. Long bolts may bind in the steel base interior as the bolt holes on inpavement bases are located very near to the galvanized steel wall. Short shipping bolts may be replaced with longer bolts by the end user at installation in order to accommodate extensions, spacers or flange rings.
Specify oversize plywood covers on light bases to be encased in concrete. The standard plywood covers are undersized by 1/32" to 1/16".
Specify extensions for installation on complete bases and top sections for installation on bottom sections. The two different items, extension and top section, may not be used interchangeably.
Specify load rings on short inpavement bases. The load ring is not standard on inpavement bases under 12" overall height. Here is a tip to remember about the design and manufacture of steel light bases. Hot-dipped galvanizing requires drainage in the steel base. Light bases that do not have conduit openings at the standard locations (2-1/2" on center from the bottom) will have drain holes installed to release the molten zinc in the shop. Holes required by the manufacturing process will be plugged before shipment.
